Es gibt viele Situationen, in denen Sie einem Client, der Ihre API benutzt, einen Fehler zurückgeben müssen.

Dieser Client könnte ein Browser mit einem Frontend, Code von jemand anderem, ein <abbr title="Internet of Things – Internet der Dinge: Geräte, die über das Internet Informationen austauschen">IoT</abbr>-Gerät, usw., sein.

Sie müssten beispielsweise einem Client sagen:

* Dass er nicht die notwendigen Berechtigungen hat, eine Aktion auszuführen.
